Africa: East African coastal regions from Somalia and Kenya, and delta of Zambezi River (Ref. 3498). Reported from Lake Rukwa basin and flood plains of Ruaha and lower Rufiji (Ref. 4967, 41366, 89002), but this species was never positively identified from Tanzania (Ref. 27292). The presence of this species in southern Africa also requires confirmation (Ref. 7248, 52193).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.6602 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00155 - 0.00977), b=3.10 (2.89 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
营养阶层 (Ref.
69278): 3.7 ±0.6 se; based on size and trophs of closest relatives
回复力 (Ref.
120179): 非常低的, 最小族群倍增时间超过14 年 (Assuming tmax > 30).
Fishing Vulnerability (Ref.
